SPECIFICATION forming part of Letters Patent No. 564,628, dated July 28, 1896.

Application filed October 7, 1895. Serial No. 564,936. (No model.)

To aZZ whom it may concern:

Be it known that I, EDMUND DENEGRE MAR- TIN, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Devices for Administering Anesthetics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved form of chloroform-inhaler or device for administering anesthetics; and the said invention consists of certain novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views.

Figure 1 represents a side elevation of the instrument in the same position as when in use, the patient being supposed to be lying down, face uppermost. Fig. 2 represents a central vertical section through the device shown in Fig. 1. Fig. 3 represents an inverted plan view of the device after the cloth sack has been removed. Fig. 4 represents a detail View in section made by a plane at right angles to the plane of Fig. 2, and shows the means of connecting the cloth sack to the bottom of the instrument. Fig. 5 represents an inverted plan view of the cloth sack detached from the instrument and shown on a smaller scale than the preceding figures, and Fig. 6 represents the framework on which the said cloth sack is mounted.

A represents a bottle containing the anesthetic a, which bottle is provided with a cap B, terminating in a conical chamber 1), connected laterally by means of the branch pipe b to the rubber tube D, through which air is blown from the bulb E. The said chamber 1) is also connected by means of the bent tubes 13 to the short delivery-tube f, projecting down through the top of the inverted cup F.

Fitting snugly in the tube B above the cap B is a small tube 0, which projects down in the bottle A nearly to the base thereof, terminating only a short distance above the base of the bottle and below the surface of the .1iquid contained therein.

The inverted cup F is provided with a handle F for convenience in holding the same, a ring F adapted to [it the bottle and hold the same, a scattering-plate F beneath the tube f to scatter the anesthetic blown therethrough, and a diaphragm f with perforations f covered with wire gauze, therethrough, as shown in Fig. 3. On the inside of this cup F are stops f to limit the'up'ward travel of the ring carrying the cloth sack, while the sides of the cup are perforated, as at f", to receive the catches k by means of which the said sack is held in place beneath the inverted cup.

11 represents a piece of hunting or other suitable cloth, which is stretched over the frame K and drawn over the bottom of said frame by means of the draw-strin g h, as shown in Figs. 2 and 5. This cloth sack is kept distended by means of the frame K, which consists of a ring it, ribs 10 and a bottom wire I0 and the said frame is provided with springcatches k, terminating in the points 10,Whi0h engage in the holes f and thus support the said frame and the sack carried thereby in the inverted cup F.

In operation the lower edge of the sack is placed over the nose and mouth of the patient and the anesthetic is blown in on the scattering-plate F and is absorbed by the cloth bag and drawn into the lungs of the patient therefrom.

In order to usethe instrument, fill the atomizer with chloroform, mixed with ether, if desired, press the bulb, and hold a few inches above the face until the patient becomes accustomed to chloroform. The sack is then placed directly over the nose and mouth and need not be removed during the entire operation. The bulb should bepressed from four to six times per minute until the patient is anesthetized. Two or three times per minute is sufficient to maintain anesthesia. Very little experience will teach any one the requirements for varying the above rules.

It will be seen that the instrument is compact, cleanly, a new cloth can be used every time, economical in the use of anesthetics, and rapid in action.

It will be obvious that oxygen maybe supplied by a slight modification of this inhaler by using a bulb with a double tube.

The various advantages of the herein-described construction will readily suggest themselves to any intelligent physician.

It will be obvious that various modifications of the herein described instrument might be made Which could be used Without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a chloroform-inhaler, the combination with an inverted-cup-shaped frame provided with a bott1e-ho1der,of a bottle held in said holder and means for blowing the contents of said bottle beneath said cup-shaped frame, and a distended cloth sack detachably connected to the bottom of said cup-shaped frame, substantially as described.

2. In a chloroform-inhaler, the combination with an inverted-cup-shaped frame provided with a scattering-plate beneath the diaphragm closing the upper end of said frame and a tube delivering the anesthetic to said scattering-plate, of a distended cloth sack detachably connected beneath said cup-shaped frame, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

EDMUND DENEGRE MARTIN.
